phosphorus assimillation in plants

Foliar application of phosphorus compounds

Phosphorus seemingly offers promise for application to leaves because the quantities of phosphorus needed are only one-tenth to one-fifth of the quantities of nitrogen needed. Besides that, the rate of absorption and the mobility in the plant are only a little less for phosphorus than for nitrogen.

This study evaluated the hypothesis that P deficiency alters N assimilation in N 2-fixing soybean plants (Glycine max L. Merr.) through effects on nodule carbohydrate status. Transport of N constituents in xylem sap, concentrations and total quantities of N fractions in plant organs, and nonstructural carbohydrate status of nodules were compared in P-sufficient (1.0 mM P) and P …

Phosphorus Basics: Understanding Phosphorus Forms and ...

Phosphorus Cycling and Transformation in the Soil. Once phosphorus enters the soil through chemical fertilizers (inorganic source), manure, biosolids, or dead plant or animal debris (organic sources), it cycles between several soil pools via processes such as mineralization, immobilization, adsorption, precipitation, desorption, weathering, and dissolution.

Phosphorus

Forms of Phosphorus available for Plant Uptake. The orthophosphates, H 2 PO 4-and HPO 4 2-, are the primary forms of phosphorus taken up by plants. When the soil pH is less than 7.0, H 2 PO 4-is the predominate form in the soil. Although less common, certain organic phosphorus forms can also be directly taken up by plants. Functions of ...

This group of microorganisms are referred to as Phosphorus Solubilizing Microorganisms (PSM). Many species of soil fungi and bacteria are able to solubilize phosphorus in vitro and some of them can mobilize phosphorus in plants (Zhu et al., 2011). PSM increases the bioavailability of soil insoluble phosphorus for plant use (Zhu et al., 2011).

Phosphorus Uptake by Plants: From Soil to Cell | Plant ...

Plant root geometry and morphology are important for maximizing P uptake, because root systems that have higher ratios of surface area to volume will more effectively explore a larger volume of soil (Lynch, 1995).For this reason mycorrhizae are also important for plant P acquisition, since fungal hyphae greatly increase the volume of soil that plant roots explore (Smith and Read, 1997).

Proteaceae grow predominantly across the southern hemisphere on soils that greatly contrast in age and plant-available phosphorus (P). Due to adaptations to a wide range of soil P concentrations, Proteaceae species in habitats with contrasting soil P concentrations have evolved unique adaptive traits that are ecologically relevant, but greatly contrasting across habitats.

Nutrient Removal — The Wetlands Initiative

In order to continually remove phosphorus, new soils need to be "built" within the wetland from remnant plant stems, leaves, root debris, and undecomposable parts of dead algae, bacteria, fungi, and invertebrates. The growth, or accretion, of new material in the wetland is the only sustainable removal and storage process for phosphorus.
